Beatenberg (Highest Alemannic: Baatebärg) is a municipality in the Interlaken district of the Canton of Bern in Switzerland.

Beatenberg is first mentioned in 1275 as super rupes. In 1281 it was mentioned as ob den fluen and in 1357 as Sant Beaten berge.

The earliest trace of a settlement in the area are some early medieval graves near the Beatushöhlen (Saint Beatus cave). According to legend, Saint Beatus was a Scottish or Irish monk who was sent to evangelize the Helvetii. After finding success in the Jura Mountains , he moved into the Beatenberg area where he defeated a dragon and established a hermitage in the cave overlooking Thun Lake.
